Step 1.2.1

Multiply $2$ by $- 4$ .

$- 8 x^{2} - 4 x - 4 \cdot - 4 - 15$

Step 1.2.2

Multiply $- 4$ by $- 4$ .

$- 8 x^{2} - 4 x + 16 - 15$

$- 8 x^{2} - 4 x + 16 - 15$

$- 8 x^{2} - 4 x + 16 - 15$

Step 2

Subtract $15$ from $16$ .

$- 8 x^{2} - 4 x + 1$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
